So I am sitting here on my old X61s, trying to get ready to give to my parents. Everything is running fine, however, every once in awhile, I get these USB Not Recognized error showing up in the notification bar. There is nothing plugged into any of the three USB ports on the machine.
I click on the notification and it shows the window below. What exactly is this "USB ROOT HUB (2 ports)", and where can I find it?
I don't really mind the notifications coming up but the DING DING...DING DING from the system thinking there is a USB device plugged in is quite annoying, and it happens randomly and often.
Any advice?
